I came across this motor the other week. It was in an old junk yard of about 60 cars. 70 Chevelle SS. It was in a serious wrecked. Car was stripped. I got the motor for $300.00 There are no #s on the front cylinder ID tab. There is a # above timing chain cover. Can anyone tell me what this # is. I'm hoping it is a replacement 396, 402, 0R 454. The # is. TK 25XAA8 The TK might stand for truck. Thanks for your help.
